Engine Trouble 2006 W-22 8.1
Left for Florida last night and about a hour into the trip engine started to backfire and hesitated while going up hills. Ran fine on flat road going back home but engine missed a lot. Coach is 10 yea...

Engine may have coil packs and not wires. Some of them fail and should set code if on input side.
I would first replace the fuel filter.
